+# 🚀 Getting Started with Podcastic
+
+Complete guide to set up and run the Podcastic application locally or with Docker.
+
+## Prerequisites
+
+### For Docker (Recommended)
+- Docker 20.10+
+- Docker Compose 2.0+
+- 4GB RAM minimum
+
+### For Local Development
+- Node.js 20+ (LTS)
+- npm or yarn
+- MongoDB 5.0+ (local or MongoDB Atlas)
+- Redis 6.0+ (local or Redis Cloud)
+
+## 🐳 Option 1: Run with Docker Compose (Easiest)
+
+### Step 1: Prepare Environment
+```bash
+cd Podcastic
+cp .env.example .env
+```
+
+### Step 2: Start All Services
+```bash
+docker-compose up -d
+```
+
+Services will be available at:
+- **Frontend**: http://localhost:3000
+- **Backend API**: http://localhost:5000/api
+- **MongoDB**: localhost:27017
+- **Redis**: localhost:6379
+
+### Step 3: Access the Application
+1. Open http://localhost:3000 in your browser
+2. Click "Create Account" to register a new user
+3. Log in with your credentials
+
+### Common Docker Commands
+```bash
+# View logs
+docker-compose logs -f frontend
+docker-compose logs -f backend
+
+# Stop services
+docker-compose down
+
+# Remove volumes (warning: deletes data!)
+docker-compose down -v
+
+# Rebuild images
+docker-compose build --no-cache
+```
+
+## 💻 Option 2: Local Development
+
+### Prerequisites Setup
+
+#### MongoDB
+```bash
+# macOS with Homebrew
+brew install mongodb-community
+brew services start mongodb-community
+
+# Or use MongoDB Atlas (cloud)
+# Sign up at: https://www.mongodb.com/cloud/atlas
+```
+
+#### Redis
+```bash
+# macOS with Homebrew
+brew install redis
+brew services start redis
+
+# Or use Redis Cloud
+# https://redis.com/try-free/
+```
+
+### Step 1: Environment Configuration
+```bash
+cp .env.example .env
+```
+
+Edit `.env` with your database credentials:
+```env
+NODE_ENV=development
+MONGODB_URI=mongodb://localhost:27017/podcastic
+REDIS_URL=redis://localhost:6379
+```
+
+### Step 2: Install Dependencies
+
+Backend:
+```bash
+cd backend
+npm install
+```
+
+Frontend:
+```bash
+cd frontend
+npm install
+```
+
+### Step 3: Run Development Servers
+
+#### Windows (Batch Script)
+```bash
+# From project root
+dev.bat
+```
+
+#### macOS/Linux (Shell Script)
+```bash
+# From project root
+chmod +x dev.sh
+./dev.sh
+```
+
+#### Manual (Split Terminals)
+Terminal 1 - Backend:
+```bash
+cd backend
+npm run dev
+# Server runs on http://localhost:5000
+```
+
+Terminal 2 - Frontend:
+```bash
+cd frontend
+npm run dev
+# Server runs on http://localhost:3000
+```
+
+### Step 4: Access the Application
+Open http://localhost:3000 in your browser
+
+## 🧪 Testing the API
+
+### Using cURL
+
+#### Register
+```bash
+curl -X POST http://localhost:5000/api/auth/register \
+  -H "Content-Type: application/json" \
+  -d '{
+    "email": "test@example.com",
+    "password": "password123",
+    "username": "testuser"
+  }'
+```
+
+#### Login
+```bash
+curl -X POST http://localhost:5000/api/auth/login \
+  -H "Content-Type: application/json" \
+  -d '{
+    "email": "test@example.com",
+    "password": "password123"
+  }'
+```
+
+#### Get User (Requires Token)
+```bash
+curl -X GET http://localhost:5000/api/auth/me \
+  -H "Authorization: Bearer YOUR_ACCESS_TOKEN"
+```
+
+### Using Postman
+1. Import the API requests from the application
+2. Set Bearer tokens in the Authorization tab
+3. Test endpoints
+
+## 📱 Testing Responsive Design
+
+### Chrome DevTools
+1. Press F12 to open DevTools
+2. Click the device toggle icon (top-left)
+3. Select different devices to test
+
+### Responsive Breakpoints
+- **Mobile**: 320px - 480px
+- **Tablet**: 481px - 1024px
+- **Desktop**: 1025px+
+
+## 🔧 Configuration Options
+
+### Environment Variables
+
+#### Backend (.env)
+```env
+# Server
+NODE_ENV=development|production
+PORT=5000
+
+# Database
+MONGODB_URI=mongodb://user:pass@host/db
+MONGODB_USER=username
+MONGODB_PASSWORD=password
+
+# Cache
+REDIS_URL=redis://host:6379
+
+# Authentication
+JWT_SECRET=your-secret-key
+JWT_EXPIRES_IN=7d
+JWT_REFRESH_EXPIRES_IN=30d
+
+# External APIs (Optional)
+PODCAST_INDEX_API_KEY=your_key
+PODCAST_INDEX_API_SECRET=your_secret
+```
+
+#### Frontend (.env)
+```env
+VITE_API_URL=http://localhost:5000/api
+```
+
+## 📚 Development Workflow

+```
+
+### Making Code Changes
+
+**Backend Changes**:
+1. Edit files in `backend/src/`
+2. TypeScript auto-compiles (with `npm run dev`)
+3. Server hot-reloads automatically
+4. Check terminal for errors
+
+**Frontend Changes**:
+1. Edit files in `frontend/src/`
+2. Vite hot-reloads in browser automatically
+3. Check browser console for errors
+
+### Build for Production
+```bash
+# Backend
+cd backend
+npm run build
+
+# Frontend
+cd frontend
+npm run build
+```
+
+## 🐛 Troubleshooting
+
+### Port Already in Use
+```bash
+# Find what's using port 3000
+lsof -i :3000
+# or
+netstat -ano | findstr :3000
+
+# Kill the process (on Windows)
+taskkill /PID <PID> /F
+```
+
+### MongoDB Connection Error
+- Ensure MongoDB is running: `brew services list`
+- Check connection string in `.env`
+- Verify credentials if using Atlas
+
+### Redis Connection Error
+- Ensure Redis is running: `brew services list`
+- Check Redis URL in `.env`
+- Test with: `redis-cli ping` (should return "PONG")
+
+### API 404 Errors
+- Verify backend is running on port 5000
+- Check frontend proxy configuration in `vite.config.ts`
+- Review VITE_API_URL environment variable
+
+### Slow Performance
+- Check browser DevTools Network tab
+- Use RTK commands for optimized output: `rtk npm run dev`
+- Clear browser cache (Ctrl+Shift+Del)
+- Check system RAM usage
+
+## 📦 Building for Production
+
+### Docker Build
+```bash
+docker-compose build --no-cache
+
+# Push to registry
+docker tag podcastic-backend myregistry/podcastic-backend:latest
+docker push myregistry/podcastic-backend:latest
+```
+
+### Manual Build
+```bash
+# Backend
+cd backend
+npm ci --only=production
+npm run build
+
+# Frontend
+cd frontend
+npm ci --only=production
+npm run build
+```
+
+## 🚀 Deployment
+
+### Using Docker
+See `.env.example` for production variables:
+```bash
+docker-compose -f docker-compose.prod.yml up -d
+```
+
+### Cloud Deployment
+- **Heroku**: See `Procfile` (if present)
+- **AWS**: Use ECR + ECS
+- **DigitalOcean**: Use App Platform
+- **Render**: Connect GitHub repo

+## ❓ FAQ
+
+**Q: Can I use SQLite instead of MongoDB?**
+A: Not currently, but can be added. Requires schema changes.
+
+**Q: How do I add more podcasts?**
+A: Currently via manual RSS URL addition. PodcastIndex API search coming soon.
+
+**Q: Can I deploy to Vercel/Netlify?**
+A: Frontend yes (static), backend no (needs server runtime).
+
+**Q: How is the audio streamed?**
+A: Direct HTTP range requests - no downloads to disk.
